Most of the information in the four-page affidavit is already widely known, but the document does shed some light on some of the gray areas in the Martin case.

According to the affidavit, Martin tried to "run home" but Zimmerman followed him, disregarding the police dispatcher's instructions not to pursue Martin. The affidavit states that Zimmerman then "confronted Martin and a struggle ensued."

According to the affidavit, Zimmerman "assumed Martin was a criminal" and "felt Martin did not belong in the gated community" where both Zimmerman and Martin lived.

On his call with the police dispatcher, Zimmerman referred to Martin and other people he perceived to be criminals as "these fucking punks," and said "these assholes, they always get away." Contrary to reports, he did not use a racial epithet.

The affidavit refers to a "witness," likely Martin's girlfriend, who was on the phone with Martin during the pursuit, and said he was "scared because he was being followed" by a strange man and "didn't know why."

According to the affidavit, "witnesses" heard "what sounded like a struggle" and "numerous calls for help," some of which were recorded on the 9-1-1 call. The affidavit states that Martin's mother has reviewed the calls and identified that it is her son's voice calling for help.
